1982 NISSAN PICKUP

Typical onset: 120,000-180,000 mi

Symptoms: Rattling noise on cold start that quiets after oil pressure builds, Rough idle or hard starting as timing retards, Check timing marks — often 5-10 degrees retarded from stretch

Fix: Replace timing chain, guides, tensioner, and front cover gasket. Usually 4-6 hours labor depending on accessories and condition of front cover studs. Guides crack and fragments can block oil pickup — don't ignore the rattle.

Estimated cost: $450-800

Symptoms: Rust bubbles behind cab corners and along rocker panels, Floor pans rot from inside-out, especially driver side, Bed floor rust-through near stake pockets and wheel wells, Frame rust at rear spring hangers in salt states

Fix: Structural rust repair requires metal replacement and welding, 8-20 hours depending on extent. Cab corners and rockers are available as patch panels. Floor pans often need custom fabrication. This is the truck's Achilles' heel — inspect thoroughly before purchase.

Estimated cost: $1,200-4,500

Symptoms: Rough idle, stalling when warm, Hard starting when hot, Vacuum lines cracked and misrouted after 40 years, Hitachi carb needs periodic adjustment and cleaning

Fix: Replace all vacuum lines with modern silicone hose, rebuild or replace carburetor, adjust mixture and idle. 2-3 hours if you're methodical with vacuum routing diagram. California emissions models have additional complexity.

Estimated cost: $300-600

Typical onset: 80,000+ mi

Symptoms: Oil seepage down front of engine, Valve cover leaks onto exhaust manifold — burning oil smell, Front cover gasket leaks often coincide with timing chain work

Fix: Valve cover gasket is 0.5 hours. Front cover requires timing cover removal, 3-4 hours. Often done together with timing chain service. Gaskets harden with age and heat cycles.

Estimated cost: $150-250 (valve cover alone), $450-800 (combined with timing)

Typical onset: 100,000-150,000 mi

Symptoms: Clutch pedal sinks to floor and won't return, Difficulty shifting or won't go into gear, Fluid leak visible at slave cylinder on bell housing

Fix: Replace both master and slave together — if one's gone, the other is close behind. Slave cylinder is 1 hour, master is 1.5 hours, bleed system. Bench-bleed the master or you'll fight air for hours.

Estimated cost: $300-500

Typical onset: 120,000+ mi

Symptoms: Clunking over bumps from rear suspension, Rear axle steering or wandering, Visible worn or cracked bushings at shackles

Fix: Replace leaf spring bushings and shackles, 2-3 hours per side. Bolts are often rusted tight — allow extra time in rust states. Greaseable shackles are an upgrade worth doing.

Estimated cost: $400-700
